Problems solved by technology
However, there are still many cables with different purposes exposed to the ground and high above the ground, suffering from long-term wind, sun, freezing and rain. The aging of the cable sheath is inevitable, which greatly shortens the life of the cable in good operation and affects the transmission performance of the cable. , and it is easy to cause a fire, causing serious damage to the cable
In recent years, the frequent occurrence of various extreme weather has shortened the service life of various cables
In order to solve this problem, people have to replace the cable again, which has undoubtedly caused a great waste of manpower, material resources and financial resources.

Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0020] In describing the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", The orientation or positional relationship indicated by "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying the referred device or positional relationship. Elements must have certain orientations, be constructed and operate in certain orientations, and therefore should not be construed as limitations on the invention. At the same time, the terms "first", "second", etc. are only used to distinguish the names of the components, and have no primary or secondary relationship, so they...

A cable protection cover provided by the present invention comprises a plurality of connecting pieces which are distributed at the top of a cable at intervals along the length direction of the cable, a cover body is arranged between every two adjacent connecting pieces, a gap is formed between each cover body and the cable, and the connecting piece is made of a fusible material. According to the present invention, the temperature of the cover body rises very high after the cover body is irradiated by the sun, and the cover body can suspend on the cable by arranging the gap between the cover body and the cable, so that the cable is prevented from being influenced by high temperature; the gap between the cover body and the cable can accelerate air circulation, so that the temperature below the cover body is further reduced; when an accidental fire disaster happens to the cable, the connecting piece made of the fusible material can be quickly melted after being heated, and the cover body directly falls on the cable, so that the top of the cable is isolated from air, a certain fire extinguishing effect is achieved, the spreading speed of flame on the cable is reduced, and enough time is provided for maintenance personnel to deal with the fire; and the cable can be prevented from being blown by wind and exposed to the sun, and the aging speed of the cable sheath is slowed down.
Description
technical field [0001] The invention relates to the technical field of protective covers, in particular to a cable protective cover. Background technique [0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires. With the rapid development of urban and rural construction, cables are spread in every corner of towns and villages. However, there are still many cables with different purposes exposed to the ground and high above the ground, suffering from long-term wind, sun, freezing and rain. The aging of the cable sheath is inevitable, which greatly shortens the life of the cable in good operation and affects the transmission performance of the cable. , and it is easy to cause a fire and cause serious damage to the cable. In recent years, the frequent occurrence of various extreme weathers has shortened the service life of various cables. For solving this problem, people have to replace the cable again, wh...
